This is the build I use for WvW roaming (and occasional dueling in guild arena)
It’s also a condition shatter build. With dire armor, it’s pretty survivable and with lots of blocks you can stay alive without stealthing.
The illusions are more survivable with a build like this.
To take down the warrior, I would try getting three illusions out and then do your F5 shatter. During that shatter, use gravity well and tides of time and all your shatters (and maybe chaos storm too). Then when the F5 ends, use those big cc skills again and hit him with the scepter 3. It’s really hard to clear all those condis – especially if you’re getting cc’d like crazy.
